Well, it is hard to tell what kind of environment variables you have. But if 
you are using environment variables to configure you could

a) reconsider and use the qmake way to set variables on the command line. This 
can be achieved using the EXTRA_QMAKEVARS_PRE and EXTRA_QMAKEVARS_POST vars 
which will result in a command line like: qmake PRE -after POST

b) you can use "export VAR" in the recipe to ask bitbake to export the VAR to 
the shell. then export VAR should show up in the generated shell script for 
do_configure and do_compile.
